Jailbreak iOS 4.0

And now I am back with the jailbreak for iOS 4.0.
iOS 4.0 is basically meant for iPhone 3Gs and up. You can still upgrade your older device but that will make it run really slow, even with some tweaks from cydia.
Without any further delay, lets move on to the jailbreak process.
For this specific jailbreak, you will need redsn0w 0.9.5 Download Here
Firmware 4.0 Download Here
And of course the latest iTunes.
To make things simple and short, the Jailbreak process is the same as we discussed on the previous post, only the version of redsn0w is different. And also the interface changes on this one.

The interface is like this.
